Something spinning around something is usually a good way to generate electricity, like wind blowing a turbine, or water spining a giant wheel or
cog.

Same way is how a generator makes electricty.

It is using natural energy and converting that to power.

There are many things that spin. The moon rotates and spins round the earth. The earth orbits the sun.

On a more smaller scale. Every car on the planet has the potential to contribute to the national grid or just power their own devices? If a
generator (with rechargable) battery is fitted into a car, the spin on the wheels (all four) could be used to generate electricty (converted from
kinetic energy powered by petrol/diesel). Then when you got back home hook up the generator to your house to transer the power you generated to your
houses, battery or the grid. This is what an alternator does but can there be more than this?

How do you charge the battery back up in the vehicle after you have drained it (assuming there was a worthwhile surplus from driving)?

They make electric drive cars that make energy during braking or going down hills to help recharge the batteries. The problem with gaining energy
from the wheels under power is that you increase the load. If you were to increase overburden it is a different story, but so far noone has been able
to figure out a way in the car setting.

Now, as you drive, an energy field builds up on the car which helps to deflect the air around it. That could be a source but the problem is that
reducing this field would increase drag. So possibly passing air through body tubes might help to create an internal energy barrior that could be
tapped for energy. I don't have any way of testing that though. As energy passes through the tube, a current might be able to be created utilizing
a zinc/copper relationship. Copper can convert energy easily either way. Then you might experience a reduction as the copper oxidizes, so you would
need a cleaning system and the impact on the air going through it might be a problem. If all cars did this, copper ions would be lost and the
pollution generated might be a problem if done on such a large scale.

These are just ideas, I studied how copper can convert one type of energy frequency to another and am playing with this idea. It is always good to
have an open mind OP. I like your thinking but it has already been thought of by those designing these things. But if you can find a way to make
this work that they did not think of, your ideas may help these people. Imagination is directly tied to creativity and creativity is tied to
advancements. Maybe someday you might find the answer, just not today. Don't get discouraged, just get interested and study their research they
have already done and someday maybe you will be working in this field of energy conversion.

Your idea with a car is basically just adding a more high-capacity battery for the alternator to charge. At first I though this was silly because
it's what our cars already do but why not? Why don't we pack our cars full of lightweight batteries to store surplus energy to then off-load
onto our home grids?

It's really not a bad idea, especially when we're trying to develop paper-thin energy storage. I guess we sort of already do this with our devices
(smartphones, iPods, ect) in our cars.

When I was growing up, we had full solar. We had panels that stored electricity on big yacht batteries which powered everything in the house. I
would have been nice if we could have plugged in our car's extra battery to transfer all that extra juice each day.

Because:

1. There are no such batteries even if there was a surplus, and
2. There isn't a surplus

Gasoline operated cars do use perhaps 4 times the energy needed to propel them, but that's not a surplus. The other 75% are in losses, mostly in the
form of excess heat, and a little bit in the form of sound (road noise from the tires). Electric motors seem more efficient but they probably aren't
if you look at the overall cycle of how the electricity is generated, which in the US a large amount is from coal and that process of generating
electricity has a lot of losses.

There are cars that recover energy from braking already as rickymouse said. That's about the best we can do directly related to the OP idea. For many
of us who don't check our tire pressure often, merely checking and adjusting the tire pressure to the recommended amount can help fuel efficiency.

A car's battery is charged by the alternator. An alternator is electric generator that converts mechanical energy into electrical energy. In the case
of an alternator in a car, the mechanical energy to turn the rotor comes from the engine. The gasoline engine is itself a machine for converting
chemical energy into mechanical energy (combustion pushing the piston).

The upshot is to generate more electrical energy to charge more batteries the engine would need to burn more gasoline. It would be more efficient to
just burn the gasoline in an electrical generator designed to do this task as efficiently as possible. In either case, the energy that is converted to
electricity originates with the chemical energy in gasoline.

There is recoverable waste energy from cars and it's being recovered in some instances like with regenerative braking systems. Here's a good website
for understanding where the energy from gasoline ends up going:

But... it already does exactly that. An alternator does exactly what you say it can't do. The only difference would be putting more
batteries in the car. If there wasn't a surplus, you wouldn't be able to start your car in the morning.

if we think of car driving at 70mph down a long road like a fast flowing river, think of both as a natural flowing process.

With the river we can place a wheel/turbine in the river the flow will then turn the river, the river will still flow and if well designed the flow of
the river will not slow too much.

Same with the car, the car is already spinning the wheels, its like a natural flow, we then just place a generator on each of the axels (drive shaft)
of each wheel, it will not cause much friction to really make a noticeable difference. So now we are using the "natural" revolution of the wheel to
generate/convert energy which is otherwise just lost as sound or something. Would this not work surely it would. You can power a light bulb by
riding a cycle hooked up to a generator.

Yes its about having good batteries too. But yes smartphones have small batteries can can power a phone for a full day. if you had a briefcase full
of these batteries, one trip to work and back could fully charge all these up and then you would have like a few months of "FREE" energy to charge
your phone with.. Its not free energy of course as you paid for the petrol to generate it in the first place.

The upshot is to generate more electrical energy to charge more batteries the engine would need to burn more gasoline. It would be more efficient to
just burn the gasoline in an electrical generator designed to do this task as efficiently as possible.

That makes more sense. It's not that it can't be done; it's just not really worth it.

Yes of course as is the Earth ... maybe my lack of knowledge is a stumbling block ... But if it says that energy is always what it is ... then the
Universe has worked out a pretty good way to expand that energy ... not being awkward ... just curious ...
